December 3rd, 1967 - the date of the first human heart transplant.
On December 3rd, 1967, the first human heart transplant was performed by Christiaan Barnard in Cape Town, South Africa.
Globally today, approximately 3,500 heart transplants are performed annually, primarily in the US.

Epistaxis - nosebleed
There are two types: anterior (most common), and posterior (less common, often requires medical attention). In severe cases the blood may travel up the nasolacrimal duct and out from the eye. Fresh blood and clotted blood can also flow down into the stomach and cause nausea and vomiting.
There are many reasons for their occurrence, the most common being trauma, drying and inflammatory reactions (e.g. due to hay fever or infection) and less commonly due to medication, alcoholism, anaemia, vitamin deficiencies and many others.
They account for, on average, 5 deaths a year in the US.
Apologies for sporadic posting~
I’ve been travelling around and studying for mid-sems, which paid off - I got a distinction!
I’ll be lining up more posts soon, so stay tuned.. and don’t forget…
Don’t worry, it’s not just you.

One horrible truth of the medical profession is that every day of your life you’ll end up letting someone down, whether it be a patient, or a friend when you end up having to cancel plans (yet again).
All one can hope at this stage is that it’ll all somehow be worth it in the end.
Phosphenes are a phenomenon characterised by the experience of seeing light without light actually entering the eye. They are often associated with optic neuritis and may be enhanced by movement or sound.
Phosphenes can be directly induced by mechanical, electrical or magnetic stimulation of the retina or visual cortex as well as by random firing of cells in the visual system. Phosphenes have also been reported by meditators; people who go for long periods without visual stimulation (also known as the prisoner’s cinema); or those who are using psychedelic drugs.
The most common phosphenes are pressure phosphenes, caused by rubbing the closed eyes. Pressure on the eye results in activation of retinal ganglion cells in a similar way to activation by light.
Another common phosphene is ‘seeing stars’ from a sneeze, blowing of the nose, a blow on the head or low blood pressure.These involve metabolic (such as from low oxygenation or lack of glucose) stimulation of neurons of the visual cortex or of other parts of the visual system. Astronauts exposed to radiation in space also report seeing phosphenes.

25 strangest things found on an X-Ray
A rare phenomenon which occurs most commonly when a foetus dies during an abdominal pregnancy and calcifies on the outside as it is too large to be reabsorbed by the body. This protects the mother’s body from the dead tissue of the baby and prevents infection.
It is not unusual for a stone baby to remain undiagnosed for decades and it is often not until a patient is examined for other conditions or a proper examination is conducted that includes an X-ray that a stone baby is found.
